The technology developed by Propulsa Innovations eliminates the need for filter changes while outperforming original filtration systems in extremely dusty environments.

Stale air enters through the base of the Epura system and passes through a high-efficiency filter. When the filter reaches a certain level of saturation, the infrasound cleaning system starts, cleaning the filter without any work interruption required.

This innovative system can be installed on operating cabins, on the air intake of diesel engines, or on other industrial filtration equipment.
